The current exploration focuses on the impact of homogeneous and heterogeneous chemical reactions on titanium dioxide-ethylene glycol (EG)-based nanoliquid flow over a rotating disk with thermal radiation. In this paper, a horizontal uniform magnetic field is used to regularise the flow field produced by a rotating disk. Further, we conduct a comparative study on fluid flow with and without aggregation. Suitable transformations are used to convert the governing partial differential equations (PDEs) into ordinary differential equations (ODEs). Later, the attained system is solved numerically by means of the shooting method in conjunction with the Runge-Kutta-Fehlberg fourth-fifth-order method (RKF-45). The outcome reveals that the fluid flow without nanoparticle aggregation shows enhanced heat transport than for augmented values of melting parameter. Furthermore, for augmented values of strength of homogeneous and heterogeneous reaction parameters, the mass transfer is greater in fluid flow with aggregation conditions.
当前的研究重点是均匀和非均匀化学反应对基于二氧化钛 - 乙二醇（EG）的纳米流体在具有热辐射的旋转圆盘上流动的影响。在本文中，使用水平均匀磁场来规范旋转圆盘产生的流场。此外，我们对有和没有团聚的流体流动进行了对比研究。采用合适的变换将控制偏微分方程（PDEs）转化为常微分方程（ODEs）。随后，通过打靶法结合龙格 - 库塔 - 费尔贝格四 - 五阶方法（RKF - 45）对所得系统进行数值求解。结果表明，没有纳米颗粒团聚的流体流动比熔化参数增大时表现出更强的热传递。此外，对于均匀和非均匀反应参数强度的增大值，在有团聚条件的流体流动中传质更大。
